Hi All
When I got this parts car you guys helped me key out the engine as a 1959 or 1960 371. Looking at this tag I believe it shows the transmission to be a 1959. Am I reading that right? What kind of transmission is this? Since it was transplanted into a 1955 would it be reasonable for this to have come with the 371 engine?

 

See if it has a Park position. If it does it will be a four speed Jetaway Controlled Coupling HydraMatic.

 

If transplanted into a 55 the park would not be visible or even there on the dash. Does it have two lines for a transmission cooler on the right-hand side, if so it is a Jet-a-way, if not it could be a Slant pan, but that tail shaft looks different to me, pretty sure it's a Jet-a-way though...Tedd

 

I haven't tried to find a Park, but it does have two lines on the right side. I hope to get the engine/transmission pulled this week and cut up the frame for scrap. Then I'll have space for a car stashed at a friends house!

It's a 1959 "Jetaway" dual coupling Hydra-Matic. As evidenced by the 59 in the serial number.
Probably came paired with the 371.

 

That seemed reasonable to me. But thank you for verifying it.
